2011 Prius Sunroof Deflector Seal Deterioration?

My 2013 don't have any drain tubes after I couldn't find them myself I had 2 different auto glass techs come out and they both couldn't find them either one of them took the headliner down and the plastic trim the runs down the sides of the front windshield off looking for them and gave up. If you have a chance maybe you can post a few more picture like with the sunroof opened . This post actually save me some serious bucks i was getting ready to buy that part for over $500 and paying someone to install it

The front seal/gasket just in front of the sunroof deflector on my Prius is shot. The first big storm of the season is coming. Will this cause water to leak inside the car? Can it be fixed without opening the sunroof? The battery is dead, so I can't open the sunroof.

 

This seems to be a common problem with Prius sunroofs. All sunroofs, just sooner with Prius.
EXPENSIVE to replace the rubber seal.

You could silicone it, but you won't be able to open it easily....

 

On mine, that isn't the water seal. I ripped that rubber out several years ago, and it has remained mostly leak-free.

When the front passenger mat was wet once, I did find possible little drain slots around the real seal, gummed up from dirt or tree debris. After cleaning, no more wetness. It is garaged most of the time, but still gets exposed to rain while driving, and endured a cross-state monsoon trip Friday without leaks.

Checking the real seal beneath the glass does require opening the roof, so the dead battery is a problem.

 

Same exact issue here. How'd it turn out?

 

A few months back I had some auto glass guy come out and seal the window up then I went ahead and bought the gaskets the guy posted above and at some point, I plan on having the same guy come out again and try and install the gasket for me

 

Any pictures of your application?

 

That's the same molding that deteriorated on my 2012 prius IV. Did you ever locate the appropriate replacement piece?

Thanks,

 

Would you be able to provide a picture of the drain holes? I am having the same issue with leaking on the passenger seat because of the sunroof. I cannot find the drains for the life of me!

 

Any update to this thread? My 2010 is doing this as well. I'm not going to replace the glass so I either need a cheap Toyota is going to do it for me or I need a different way to fix it. I live in the PNW and when it rains, the seal sticks up like a rodent has been eating it but I know they aren't. When it's dry the seal goes back down and I forget about it. Well, the rain has arrived and my roof looks like it is growing antlers because it's sticking up again. I hope it doesn't leak. It didn't last year but it looks worse this wet season.

 

I'm sitting in the Toyota dealership now dealing with this. I've had the problem for about 8 months with no water leakage, but now that we're experiencing cold weather, I'm getting condensation, frost and ice INSIDE the car and it's therefore become a safety hazard (I don't have a garage so the car is parked outside). Clearly it's a defect, so let's see how Toyota deals with it.

 

Was anything resolved? Can It be resealed? I also have a 2010 with curling weatherstripping on roof glass

 

I have the same issue. I’m in Portland Oregon and this seemed to happen after our most recent freeze. It’s horrible I have to replace the whole sunroof. Quoted over $3000. Is there anything I can do?

 

I have a 2013 with the same problem mine was leaking water bad. I found a local windows guy came out and glued the top closed as a temporary fix that was almost 2 years ago hasn't leaked since he said he would come out and fix it right if I get the parts for around $300 labor. I been trying to research the parts can someone confirm which of these parts they think are the ones needed to get the job done?

Would the sunroof seal on the Toyota overstock site work for a new seal?? Around the sunroof glass

 

any luck at all? My seal is currently bunching but was told by dealership to replace the whole sunroof

 

I never went beyond trimming off the warped rubber as cleanly as I could (2012 Prius Three), and then leaving it alone, as mentioned here several years ago. The warped piece was not the actual weather seal, but just some trim. When there was a water leak, I found and cleaned some grooves along the seal, and experienced no more leak. Though it was garaged most of the time.

Traded it in last month towards a new RAV4 Prime. Even though the salescritter and I talked looked at and talked about it, the trade-in value was not dinged for this unrepaired trim issue.

 

Well, here we are in 2025! The seal around the glass sunroof deflector of my 2012 Prius detached last night without any warning signs of warping, deteriorating, or coming loose before full length of the deflector seal came off. I was driving on the beltway and kept hearing a thudding noise but it took me a while to figure out it was that seal flapping against roof. Drove the rest of the way home with one hand on the steering wheel and one freezing, cold hand out of my sunroof holding onto that strip thinking it would come off completely if I didn't. I thought I could just reattach it, like the glass would slide into a groove on the seal strip and I could pop it back into place. It obviously doesn't and was really stretched out by the time I tried anyway. Googled the issue and found this thread.

I bought this car used in 2015 from a dealership in northern VA. I will reach out to them to see what they say. No extra warranty purchased. I will share this thread with whoever I speak with about this issue. Maybe I will reach out to Toyota US if I get nothing from the dealership. I can report back here on what I am told.

I’m in Washington, DC and I always park on the street. We have the full gamut of winter weather ranging from mild winters with little to no snow and barely any freezing temperatures (sometimes for years on end), then we’ll get some winters with extended below freezing temperatures and polar vortexes, and occasionally (every ten years or so) we’ll get a foot or more of snow. Summers are almost invariably hot and humid with July/August usually in the 90’s F, sometimes 100 F.

I just read every single post on this thread and some people have had problems with leaking when the seal was removed, and some have not. Others fixed that issue by clearing the drain holes. We get a lot of rainstorms and wind here so I think I will clear the accumulated tree debris out of that are under the deflector and make sure the drain holes are clear while I sort this issue out.
